Chelsea manager Thomas Tuchel has been impressed by four players in particular during pre-season.
The 47-year-old has been hard at work with players who were not involved in summer tournaments such as Euro 2020 or Copa America.
The Champions League winners are hoping to hit the ground running in the Premier League this season.
Per football.london, Callum Hudson-Odoi, Ruben Loftus-Cheek, Armando Broja and Dujon Sterling are four who have caught Tuchel's eye so far.
Whether any of those players will be regulars in the coming season is up for debate, as they may have several first team stars ahead of them in the pecking order when everyone is fit.
